How to emulate a Number Pad and 3 Button Mouse?
Blender has options that allow you to emulate both of these features. If you go into the User Preferences view and select the 'Input' tab, you should see a bunch of options on the left side of your screen. To use the numbers across the top of your keyboard instead of a number pad, select 'Emulate Numpad.' To emulate the third mouse button, select 'Emulate 3 Button Mouse.' What this does is allows you to press the Alt key while using your left mouse button, and have it behave just like the middle/third mouse button.



Ultimately however, if you're going to be using Blender heavily, you're going to want to get a real three button mouse and/or a numpad. I would personally heavily recommend getting a USB or wireless three-button mouse from a office supply store--they're really cheap, and it saves a ton of time over the Alt-click setting.
